Synopsis

Description

The dim class represents a single dimension tag/dimension exponent pair. That is, dim<tag_type,value_type> is a pair where tag_type represents the fundamental dimension being represented and value_type represents the exponent of that fundamental dimension as a static_rational. tag_type must be a derived from a specialization of base_dimension. Specialization of the following Boost.MPL metafunctions are provided

mpl::plus for two dims

mpl::minus for two dims

mpl::negate for a dim

These metafunctions all operate on the exponent, and require that the dim operands have the same base dimension tag. In addition, multiplication and division by static_rational is supported.
